Hair growth effects of Sangmosu have been evaluated in C57BL/6 mice. Animals were topically treated with Sangmosu (50 or $100{;}{mu}l/mouse$) for 40 days on the back of shaved area. Twenty days after treatment, hair growth effects were significantly observed in both female and male mice. There was no sex difference although 30 days after treatment female mice were shown to be more effective at the dose of $50{;}{mu}l/mouse$ than males. These data demonstrate that Sangmosu is very effective in hair growth effects in animals and thus it may be applicable to humans.
